SEALING TOOL QR CHUCK FOR BOTTLES.

To all whom it may concern Be it known that I, GUSTAVE LIDSEEN, acitizen of the United Statesfand a resident of the city of Chicago, inthe county of Cook and State of Illinois, have invented certain new anduseful Improvements in Sealing Tools or Chucks for Bottles; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, and to the numbers of reference marked thereon, which form apart of this specification.

This invention relates to improvements in bottle sealing chucks of thatclass set forth in my prior application for patent therefor, filed onthe 30th day of August, 1911, Serial No. 646,945. The constructionillustrated in said former application, embodies the hinged chuckmembers, each carrying two arms or levers adapted to be gripped by thehands to operate the device in sealing, necessitating the use of thegripping pressure exerted by the hands, and necessitating considerablestrength of grip.

The object of this invention is to afford a construction whereby thechuck is applied and operated by direct downward pressure, and withoutthe necessity of exerting a gripping pressure in sealing.

The invention also has for its object a construction in which thegripping action is limited to prevent undue pressure being exerted uponthe bottle or sufficient to injure the sealing cap.

The invention is illustrated in the drawings, and is hereinafter morefully pointed out and definedin the appended claims.

In the drawings: Figure 1 is a side elevation of a device embodying myinvention, showing the same applied ready for sealing. Fig. 2 is acentral section thereof, illustrating the position of parts before theapplication of sealing pressure. .Fig. 3 is a similar view, illustratingthe closing of the seal. Fig. 1 is a bottom plan view of the same. Fig.5 is an enlarged section taken on line 55 of Fig. 2. Fig. 6 is anenlarged, fragmentary detail section illustrating the closing of theseal.

gether along a central line, and each shaped on its interior to fit tothe mouth of a bottle and to press the sealing cap 3, in place thereon.Said chuck members are provided on diametrically opposite sides of eachother with integral outwardly extending brackets 4e, cored on the underside to receive thereinto the inwardly projecting ends 5, of levers, theouter ends 6, ofwhich are the hand levers whereby the device isoperated. Said lev'ers are fulcrumed in said brackets by means offulcrum pins 7 Integrally connected with each of said levers, andextending obliquely outwardly and downwardly from the fulcrum pin 7, isa slotted arm 8, at the extremity of which is articulated a link 9,which at its other end engages in the slotted end 10, of a lever 11,fulcrumed in said bracket and projecting inwardly and affording a yokeat its opposite extremity to fit chuck members 12, carried by saidsemi-eireular chuck members when the chuck is closed, form asubstantially continuous ring about the neck of the bottle. Springs 13,are seated in'suitable recesses in the semicircular chuck members tobear downwardly on said sliding chuck members 12, to hold the same atthe downward limit of travel, and, as shown, a pin 14, extends through asuitable aperture in eachsliding chuck member and in the semi-circularchuck members 1 and 2, respectively, to hold said chuck members at alltimes in proper relation, though ermitting free relative movement outwarly and into a suitable socket therefor inwardly of the sliding chuckmembers with respect to the semi-circular chuck members.

Seated in the inner periphery of the sliding chuck members 12, are pins15, the heads of which project radially inwardand are con- .caveon'their upper sides to recelve the edge 3 of the sealing cap, and crimpthe same inwardly, and to facilitate such inward bending of the sealingcap, an ofl'set or shoulder 16, is provided in each of said slidingchuck members tending to incline the edge of the cap inwardly When'thesealing tool is applied thereto.

As shown, means are provided also for starting a tearing portion at theedge of the sealing cap. For this purpose, as shown, inwardly and"upwardly projecting angular points 17, affording knives are provided inone of the sliding chuck members 12, substantially in a line with itsoperating handle or lever, and between the two knives 17, is anoutwardly projecting lip 18, adapted to engage the edge of the capbetween said two knives, and to. deform the same slightly outwardly andupwardly to permit of ready insertion of an openingtool therebeneath, asillustrated at X, in Fig. 10, the cuts formed by said knives beingindicated by Y, in the same figure.

lihe operation is as follows: The bottle, shown as the ordinary milkbottle provided with the usual shoulder on which may be laid a paraffinor other suitable stopper 19, has first applied thereto the soft metalor other suitable sealing cap 3, having the mantle or peripheral flangethereof extending well down over the head of the bottle neck. Thesealing tool is lifted by its handles 6, and applied over-the top of thebottle and seal, as shown in Figs. 1, 2 and 3. The handles are nowforced down, as shown in Fig.

i 3,1-forcing the ring composed of the sliding chuck members 12,upwardly by engagement of the yoked end of the levers 11, therebeneath',as shown in Figs. 3 and 4, such' up- I ward movement of sald ringbringing the projecting heads of the pins 15,"into engagement with themantle of the seal, and rolling the same inwardly and upwardly intoposi- 'tive engagement beneath the bead of the bottle neck. Suchinwardrolling is assisted by the ofiset '16, and the caps preferably areformed with a peripheral deformation or offset adjacent to, or slightlyabove the ofiset 16,

so that the closing of the seal preparatory to applying the pressurethereon, acts to tip or incline the edge of the sealing cap inwardly.With the closing of the seal, the knife points 17, and the lip 18.engaging the mantle at one side thereof, efi'ects a deformation therein,said knife point starting an incipient cut in the metal, or creasing thesame preparatory to tearing, while the lip or projection 18, acts toroll the same outwardly, affording a recess therebeneath as indicatedatX, in'Fig. 10, to permit the ready insertion of a tool, or othersuitable appliance for tearing the cover suficiently to permit of readyremoval.

It is to be observed that the springs 13, are

35.111131 chuck mem-' sufiicient to force the niaeaee against theextendedinner ends 5, of said levers, serving to limit the throw thereofin sealing, and preventing such pressure being applied at any time ascould by any possibility injure either the seal or the bottle.

Of course, details of the construction may be varied. I have shown but apreferred form of my invention, and I therefore do not purpose limitingthe patent granted on this application, otherwise than necessitated bythe prior art.
